Home additions in La Riviera typically run between $95,000 and $210,000 depending on whether you’re adding a bump-out, a full room, or a second story. Most projects here take 3 to 7 months from permit to final walkthrough. If you live in La Riviera and you’ve been weighing whether to add on versus move, you’re in a unique spot: your lot is probably bigger than anything you’d find for double the price closer to downtown Sacramento. We’re Lodgewick ADU Sacramento, and our Home Addition Contractor team has worked through enough La Riviera projects to know what your house, your soil, and your county inspectors will throw at us. Call (279) 256-1973 and we’ll give you a written price before any work begins.
Why Lodgewick ADU Sacramento Is La Riviera’s Preferred Home Addition Contractor Company

La Riviera sits in unincorporated Sacramento County, which changes the rules around what you can build and where. County permitting moves differently than city permitting, and you want a contractor who already knows the county’s plan-check quirks. We do. Russ Delmar has walked enough La Riviera lots along La Riviera Drive and Mira Del Rio Drive to know which side yards can handle a second story and which ones need a conversation with the county about setbacks.
Our La Riviera customers come back to us because the price on the proposal is the price on the final invoice. That’s The Kingswell Guarantee, and it’s in writing on every job. We also give you a real arrival window for our crews, we leave the job site cleaner than we found it, and every build includes a written 365-Day Done Right Promise. If something isn’t right, we come back and make it right. Free. No arguing about whose fault it is.
When you call our office, a live person picks up. Not a voicemail loop, not a chatbot. That matters when you have a question about your permit status or a sub-contractor’s schedule and you want an answer now, not tomorrow.
Sunroom Addition in La Riviera
A sunroom addition in La Riviera usually runs $45,000 to $85,000 and adds 150 to 300 square feet of conditioned space without the full cost of a traditional room addition. That range covers a stick-built sunroom on a slab with proper insulation and a mini-split for the 100°F+ summer days we get here.
Designing Around La Riviera Summers
The biggest mistake we see in La Riviera sunrooms is under-specifying the glass. Cheap single-pane windows turn the room into a greenhouse by 1 p.m. in July. We spec low-E double-pane glass, add ceiling fans, and size the mini-split for the room’s actual solar load, not just its square footage.
Sunroom Financing Reality Check
A sunroom is not a garage conversion and it’s not a full room addition. Lenders sometimes get fuzzy on that. We’ll give you a line-item quote you can hand to your lender with exactly what’s included, from the concrete pour to the final paint.
Room Addition Contractor in La Riviera

A room addition contractor in La Riviera handles the full-scope work: foundation, framing, roofing, electrical, plumbing, insulation, drywall, and finish. A single ground-floor room addition here typically costs $70,000 to $130,000 depending on whether you’re adding a bedroom, an office, or a family room with a wet bar.
Working With 1950s to 1970s Ranch Footprints
Most La Riviera homes were built between the 1950s and 1970s on slab foundations with simple gable roofs. That’s actually good news for a room addition: the rooflines are easy to tie into, and the lots are big enough that we rarely have to fight the setback lines. The catch is asbestos. If we’re cutting into original drywall or flooring, we test first. County inspectors here expect it.
Foundation Upgrades on Original Slabs
Some original slabs in La Riviera have settled or cracked over six decades. We’ll do a foundation inspection before we quote your addition, so you don’t get a surprise change order when the concrete gets opened up. That’s part of the written price we give you up front.
Trusted Brands We Service in La Riviera
Lodgewick ADU Sacramento works closely with established prefab and materials brands that fit La Riviera’s lot sizes and existing ranch-home aesthetics. We’ve built with Dvele, whose panelized construction speeds up framing on tight lots. Cover and Boxabl work well when you want a detached addition with a predictable timeline and a clean, modern look. Because we know these systems well, we can tell you honestly whether a prefab path or stick-built makes more sense for your specific property, your budget, and what the county will approve. That’s the kind of straight answer that saves La Riviera homeowners thousands.
Common Home Addition Contractor Problems We See in La Riviera Homes
- Asbestos in original drywall and flooring: Homes built before 1980 in La Riviera frequently contain asbestos in texture coats, vinyl flooring, and insulation. Testing adds a few hundred dollars; skipping it adds a stop-work order from the county.
- Slab foundations with hidden cracks: Six decades of Sacramento Valley clay shifting under original slabs means we often find hairline cracks that need sealing before new framing goes up.
- Roof tie-ins on shallow gable pitches: The simple gable roofs common in La Riviera look easy to tie into, but shallow pitches collect leaf debris and standing water where the new roof meets the old. We add crickets and proper flashing every time.
- Drainage around the new footprint: La Riviera’s wet winters dump enough rain to pool against a new slab if the grade isn’t right. We typically add French drains on the low side of the addition to keep water out of the new crawlspace or slab edge.
Pricing for Home Addition Contractor in La Riviera, CA
Here’s what we tell La Riviera homeowners when they call for a ballpark: a bump-out addition runs $45,000 to $75,000. A single ground-floor room addition runs $70,000 to $130,000. A second story addition runs $150,000 to $300,000 because you’re adding structural support, stairs, and re-roofing a larger area. A garage addition or garage conversion runs $60,000 to $110,000. The final number depends on foundation condition, the type of finishes you choose, and whether the county requires any grading or drainage work. You won’t need to call us just to get those numbers, and when we do come out, we’ll put the real price in writing before any work starts. Free estimate, no pressure. Call (279) 256-1973.

Yes. La Riviera is unincorporated Sacramento County, and every home addition we build there goes through county permitting, not city of Sacramento permitting.

La Riviera pricing is slightly lower than Roseville or Folsom because the lots are flatter, the existing rooflines are simpler, and county permitting fees are generally less than city fees.

Yes, every room addition in unincorporated Sacramento County requires a building permit, and if you’re adding plumbing or electrical, those need separate permits too. We pull every permit, schedule every inspection, and make sure the county signs off before we call the job done. You won’t have to deal with the county counter yourself.
